Description of the Appliance

4 English

Danger

Never touch the mains plug and the

socket with wet hands.

The appliance must not be used if the

power cable or important parts of the

appliance, e.g. safety devices, high-

pressure hoses, spray guns, are dam-

aged.

The appliance may not be used in areas

where a risk of explosion is present.

If the appliance is used in hazardous ar-

eas (e.g. filling stations) the corre-

sponding safety provisions must be

observed.

Check the power cord with mains plug

for damage before every use. If the

power cord is damaged, please arrange

immediately for the exchange by an au-

thorized customer service or a skilled

electrician.

High-pressure jets can be

dangerous if improperly

used. The jet must not be

directed at persons, ani-

mals, live electrical equipment or at the

appliance itself.

The jet must not be directed at other

persons or directed by the user at him/

herself to clean clothing or footwear.

Never use the appliance to clean ob-

jects containing hazardous substances

(e.g. asbestos).

Vehicle tyres or tyre valves are suscep-

tible to damage from the high-pressure

jet and may burst. The first indication of

this is a discolouration of the tyre. Dam-

aged vehicle tyres/tyre valves are highly

dangerous. Ensure that a distance of at

least 30 cm is observed when cleaning

with the jet!

Never draw in fluids containing solvents

or undiluted acids and solvents! This in-

cludes petrol, paint thinner and heating

oil. The spray mist thus generated is

highly inflammable, explosive and poi-

sonous. Do not use acetone, undiluted

acids and solvents as they are aggres-

sive towards the materials from which

the appliance is made.

몇Warning

Check the high-pressure hose for dam-

age before every use. Please arrange

for the immediate exchange of a dam-

aged high-pressure hose.

High-pressure hoses, fixtures and cou-

plings are important for the safety of the

appliance. Only use high-pressure hos-

es, fixtures and couplings recommend-

ed by the manufacturer.

This appliance was designed to be used

with detergents which are supplied or

recommended by the manufacturer.

The use of other detergents or chemi-

cals may compromise the safety of the

appliance.

Unsuitable extension cables can be

hazardous. Only use extension cables

outdoors which have been approved for

this purpose and labelled with a suffi-

cient cable cross section:

1 -10 m: 1.5 mm2; 10 - 30 m: 2.5 mm2

Note

The appliance must not be operated by

children or persons who have not been

instructed accordingly.

The operator must use the appliance

properly. When working with the appli-

ance, he must consider the local condi-

tions and pay due care and attention to

other persons, in particular children,

who are nearby.

Observe a distance of at least 30 cm

when using the jet to clean painted sur-

faces to avoid damaging paintwork.

Cleaning operations which produce oily

waste water, e.g. engine washes, un-

derbody washes, may only be carried

out using washing stations equipped

with an oil separator.

Wear protective clothing and safety

goggles to protect against back spray

containing water or dirt.

Safety instructions

English 5

Never leave the appliance unattended

when it is in operation.

Make sure that the power cable or ex-

tension cables are not damaged by run-

ning over, pinching, dragging or similar.

Protect the power cable from heat, oil,

and sharp edges.

The connection between the power ca-

ble and extension cable must not lie in

water.

All current-conducting parts in the work-

ing area must be protected against jet

water.

The appliance may only be connected

to an electrical supply which has been

installed in accordance with IEC 60364.

The appliance may only be connected

to alternating current. The voltage must

correspond with the type plate on the

appliance.

The minimum fuse rating required at the

socket outlet is 13 A (slow-blow).

To avoid accidents due to electrical

faults we recommend the use of sockets

with a line-side current-limiting circuit

breaker (max. 30 mA nominal tripping

current).

The plug and coupling of the extension

cable used must be watertight.

Always fully unroll electrical cables from

the cable drum.

Safety devices serve to protect the user

and must not be rendered inoperational or

their functions bypassed.

The switch prevents unintented starting of

the appliance. Stop the appliance during

breaks or after operation.

The safety catch on the handgun prevents

the appliance from being switched on unin-

tentionally.

Safety Devices

6 English

ÎAssemble appliance as shown on

page 10.

ÎPush out the safety clip in the handgun

using e.g. a small screwdriver.

ÎJoin high pressure hose and handgun

together.

ÎPush clip in until it engages and check

that it is securely fastened by pulling on

the high pressure hose.

For connection values, see type plate/tech-

nical data.

Observe regulations of water supplier.

ÎUse a fibre-reinforced hose (not includ-

ed) with a standard coupling:

- Minimum diameter, 1/2 inches (13 mm)

- Minimum length, 7.5 m.

ÎScrew the coupling unit (supplied) to the

water connection on the appliance.

ÎPush the water supply hose onto the

coupling unit, then connect it to the tap.

몇Caution

Never operate the high-pressure cleaner

when the tap is turned off as dry running will

damage the High pressure pump.

If the water supply is not clean, the Kärcher

water filter must be used (special accessory

- order No. 4.730-059).

When fitted with the appropriate accesso-

ries, this high-pressure cleaner can draw in

surface water, e.g. from water butts or

ponds (max. suction height 0.5 m).

ÎUse the Kärcher water filter to protect

the high pressure pump and accesso-

ries (special accessories). This filter re-

moves dirt from incoming water.

ÎAs the standard coupling system is not

suitable for use in suction mode, the

Kärcher suction hose with integrated fil-

ter should be used instead (special ac-

cessory) and suspended inside the

water butt.

ÎRemove air from appliance before oper-

ation: Switch on the appliance when the

high pressure hose is not connected

and run it until the water which discharg-

es from the high pressure outlet is free

of bubbles. Switch off appliance and

connect high pressure hose.

Note: The appliance deaerates faster if

you first fill the suction hose with water.

ÎScrew high pressure hose on to high

pressure outlet on appliance.

ÎPush the appropriate spray lance on to

the handgun and fasten it by turning it

through 90°.

ÎOpen tap.

ÎPlug in the main plug.

ÎSet main switch to “I/ON”.

ÎPress safety catch on the handgun to

release it and pull lever.

몇Risk of injury

The handgun is subjected to a recoil force

when the water jet is discharged. Make sure

that you have a firm footing and are also

holding the handgun and spray lance firmly.

Carrying out the most common cleaning

tasks.

ÎTurn the Vario Power nozzle to required

high pressure position (Min–Max).

For strong contaminations.

Note

Detergent can only be added when the ap-

pliance is being operated in low pressure

mode.

All washing brushes supplied by Kärcher

are designed for use with detergents.

switch the appliance on for approxi-

mately one minute once the spray lance

has been removed and rinse until water

runs clear.

ÎRelease the lever on the handgun.

ÎSet the appliance switch to "0/OFF“.

ÎTurn off tap.

tion using flat-nose pliers and clean with

running water.

ÎRemove filter from suction hose for de-

tergent and clean with running water.
